Hi Karl,
I think the Air Ministry used standard switches, as used in houses at the time, although the voltages might have been different of course. If they were not the same as standard house switches they were very similar. When I was working on the restoration of the DH9 we used house switches as substitutes for the Air Ministry switches, and they are virtually identical, at least in appearance.
The correct Air Ministry aircraft switches have AM marked in black ink on the rear face, as you alluded to.
Regards,
David.
